Anatomical terminology

The posterior tibial artery of the lower limb carries blood to the posterior compartment of the leg and plantar surface of the foot, from the popliteal artery via the tibial-fibular trunk. It is accompanied by a deep vein, the posterior tibial vein, along its course.

Branches[edit]

The PT gives rise to medial plantar artery and lateral plantar artery.

In addition a calcaneal branch to the medial aspect of the calcaneus.

Palpation of the posterior tibial artery pulse[edit]

The posterior tibial artery pulse can be readily palpated posterior and inferior to the medial malleolus and is often examined by physicians when assessing a patient for peripheral vascular disease. It is very rarely absent in young and healthy individuals; in a study of 547 healthy individuals only one person did not have a palpable posterior tibial artery.[1] It is easily palpated over Pimenta's Point.
